Caverns of time quest chain

[Pacekeeper]

Icecrow server, guys sorry if this is the wrong place to ask but is the caverns of time quest chain broken? I completed the first quest 'To The Master's Lair' and than got stuck on second quest where a npc is suposed to spaw and guide you trough caverns of time, need to enter black moras to get Karazhan key. Any clues?
